1·Any such deviations could give hints of the postulated particle known as the axion, which could in turn prove the existence and nature of dark matter.
任何偏差都可能帮我们找到假想的粒子比如轴子，然后进一步验证暗物质的存在和它的性质。
2·The experiments in astrophysics and astronomy give limits [for the axion's existence] over long distances very stringently, but not for the short distances.
天体物理与天文学的实验在远距离上有严格的限制(对轴子存在)，但是短距离上并没有。
3·Other axion searches are ground - based.
对轴子的其他搜寻活动是在地面上的。
